Dislocation of unsp acromioclav jt, > 200% displacmnt, subs

This code signifies a severe, chronic dislocation of the acromioclavicular (AC) joint, where the clavicle is displaced upward by more than twice its normal width relative to the acromion. This injury has been previously treated or evaluated, and the patient is presenting for follow-up care, such as rehabilitation, cast change, or monitoring of healing.

Apply this code for patients presenting for subsequent treatment of an AC joint dislocation that was initially diagnosed as a Type V or VI injury (based on Rockwood classification) or otherwise documented as having greater than 200% displacement. This includes encounters for ongoing management after initial surgical repair or conservative treatment.

• Ensure documentation specifies "greater than 200% displacement" or a Rockwood Type V/VI injury for accurate coding.
• The 7th character "D" indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Confirm the laterality (unspecified in this code) is not documented, otherwise a more specific code should be used.
